From 44d306e1508fef6fa7a6eb15a1aba86ef68389a6 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Sun, 10 Dec 2006 02:21:26 -0800 Subject: [PATCH] user of the jiffies rounding code: JBD This patch introduces a user: of the round_jiffies() function; the "5 second" ext3/jbd wakeup. While "every 5 seconds" doesn't sound as a problem, there can be many of these (and these timers do add up over all the kernel). The "5 second" wakeup isn't really timing sensitive; in addition even with rounding it'll still happen every 5 seconds (with the exception of the very first time, which is likely to be rounded up to somewhere closer to 6 seconds) Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- fs/jbd/transaction.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'fs/jbd') diff --git a/fs/jbd/transaction.c b/fs/jbd/transaction.c index d38e0d5..cceaf57 100644 --- a/fs/jbd/transaction.c +++ b/fs/jbd/transaction.c @@ -55,7 +55,7 @@ get_transaction(journal_t *journal, transaction_t *transaction) spin_lock_init(&transaction->t_handle_lock); /* Set up the commit timer for the new transaction. */ - journal->j_commit_timer.expires = transaction->t_expires; + journal->j_commit_timer.expires = round_jiffies(transaction->t_expires); add_timer(&journal->j_commit_timer); J_ASSERT(journal->j_running_transaction == NULL); -- cgit v1.1
